The kernel is the central module of an operating system (OS), which connects the system hardware to the application software(Beal, V. , n.d., para. 1 ). According to (RedHat , n.d., para. 2 ) “The kernel is so named because—like a seed inside a hard shell—it exists within the OS and controls all the major functions of the hardware, whether it’s a phone, laptop, server, or any other kind of computer”. The better you understand the kernel, the better you code. Graphical representaton of Linux Kernel working as a bridge between hardware and user processes. (RedHat , n.d., para. 6 ) states: You can think of a Linux machine as having 3 layers: The hardware: The physical machine—the bottom or base of the system, made up of memory (RAM) and the processor or central processing unit (CPU), as well as input/output (I/O) devices such as storage, networking, and graphics. The CPU performs computations and reads from, and writes to, memory. The Linux kernel: The core of t...
